Wavefonix released 3340 Voltage-Controlled Oscillator


VCO with Original CEM3340 ArchitectureFeaturing the legendary CEM3340 IC, the 3340 Voltage-Controlled Oscillator (VCO) module offers that classic, rich analog sound found in many famous synthesizers from the past, along with a wide range of sound shaping and modulation possibilities.


  • Original CEM3340 (Rev. G) architecture for a rich, analog sound.
  • Four simultaneous, buffered 10Vpp (±5V) waveforms including DC-coupled ramp, triangle and sine and pulse outputs, with a controllable PW and PWM CV input (0V to 5V). Pulse output is
  • derived from the CEM3340’s triangle waveform using external circuitry.
  • Coarse and fine frequency control knobs provide an adjustable frequency range of approximately nine octaves (approximately 8Hz to 16KHz).
  • 1V/octave input providing accurate tracking over more than ten octaves.
  • Controllable CV inputs for linear and exponential FM.
  • Comparator-based soft (with adjustable level) and positive/negative hard sync inputs offer versatility; allowing the VCO to be synced to many different types of sources, such as envelopes,
  • sine waves, gate signals and so on.
  • Vertical symmetry and roundness of sine wave can be independently adjusted.
  • Ergonomic design.
  • Hand-built and tested in the UK.
